.0.5-five% Mineral salts……………………………1% Free of charge proteins…………………………..0.five-1% The system dependable while in the formation of mucoadhesive bond Action one : Wetting and swelling in the polymer(Get hold of stage) Step two : Interpenetration among the polymer chains as well as the mucosal membrane Step 3 : Formation of bonds between the entangled chains (both often called consolidation stage) Electronic theory Wetting idea Adsorption theory Diffusion theory Fracture concept Advantages about other controlled oral controlled release systems by virtue of prolongation of residence of drug in GIT. Targeting & localization of the dosage form at a selected website -Pain-free administration. -Minimal enzymatic exercise & stay clear of of 1st move metabolism If MDDS are adhere way too tightlgy as it is undesirable to exert an excessive amount of drive to get rid of the formulation right after use,otherwise the mucosa may be hurt. -Some patient suffers unpleasent sensation. -Sad to say ,The dearth of standardized techniques often contributes to unclear results. -high-priced drug delivery system
